0.92 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

For centuries the warm glow of Ceylon yellow sapphires has been treasured by royalty and connoisseurs, bridging ancient traditions and contemporary taste. This sapphire carries that same sense of history, a gemstone whose lineage can be traced back to the storied mines of Sri Lanka where gem hunting was once a royal pursuit. In a time when gemstones were entrusted from generation to generation as symbols of wisdom, prosperity, and good fortune, this yellow sapphire stands as a reminder of those enduring values. The soft, sunlit hue evokes classical ideals of beauty, making it a perfect choice for someone who favors designs that feel timeless rather than transient. At The Natural Sapphire Company we celebrate that legacy, and this stone has been carefully selected for its combination of provenance, purity, and the kind of character that only an untreated, natural gem can possess.

This transparent Other certified Yellow sapphire weighs 0.92 carat, with dimensions of 6.59 x 4.72 x 3.11 mm, and is cut in an elegant cushion shape that marries vintage charm with modern brilliance. The mixed brilliant cut enhances its optical performance by blending a faceting scheme that promotes both depth and scintillation, and the excellent polish ensures that each facet speaks with clarity. Clarity is graded as very very slightly included, evaluated at eye level, which means the stone reads as exceptionally clean to the naked eye while retaining the small natural identifiers that confirm authenticity. The color intensity is medium intense, a tone that balances vibrancy and subtlety, and importantly this sapphire has received no enhancement, preserving the integrity of its natural origin in Ceylon Sri Lanka. For collectors who value authenticity and history, an untreated gem from a legendary source is a rare and meaningful find.

The reason this yellow sapphire sparkles with a character that feels unmatched begins in its very structure, and the science of light and crystal explains the magic. Sapphires are composed of corundum, a trigonal crystalline form of aluminum oxide, and their atomic arrangement creates a high refractive index, typically around 1.760 to 1.770, which governs how light bends as it enters and exits the stone. That high refractive index yields strong brilliance, while a modest dispersion produces flashes of spectral color when the stone is well cut. Corundum also exhibits slight birefringence, up to about 0.008, a property that can add subtle optical complexity to the way light plays across facets. When a skilled cutter applies a mixed brilliant faceting scheme to a cushion outline, the result is a conversation between broad flashes of light and lively scintillation. The pavilion facets return light like mirrors, the crown facets spread it into a soft, lively glow, and the junctions of those facets produce scintillation that feels both fiery and sophisticated. With an excellent polish the surface loses nothing to haze or abrasion, and the untreated nature of the stone allows its intrinsic optical behavior to sing freely without interference from heat or diffusion treatments.

Choosing this yellow cushion sapphire from The Natural Sapphire Company is to choose a gem that will age gracefully, to become part of a story rather than a passing trend. Its classical cushion silhouette complements settings that honor heritage, a simple solitaire for quiet elegance, a halo for vintage glamour, or a bespoke heirloom piece designed to be passed down through generations. Beyond its beauty, the corundum hardness of nine on the Mohs scale means it is suited for daily wear, a dependable companion that keeps its polish and brilliance through the years. For those who collect for both aesthetic and historical reasons, an untreated Ceylon sapphire of this quality represents lasting value and personal significance. If you would like to see this gem in person, to study how its facets catch the light under different conditions, or to explore settings that will showcase its glow for generations to come, The Natural Sapphire Company is ready to assist with expert guidance and a commitment to provenance and craftsmanship.
